Stump Grinder

Environmental Benefit of Excavator Stump Grinding

It is often quicker and easier to rip a stump out of the ground with an excavator, however grinding the stump has benefits

• The organic material from the stump is left in place to decompose and enrich the soil, as compared with the alternative of ripping the stumps out of the ground with the excavator and then burning or otherwise disposing of the stump.
• Ripping the stump out with the excavator removes the underground root structure and leaves the ground prone to erosion
• Stumps ripped from the ground are difficult to cut - the soil in the roots blunts chainsaws.
• Many ripped stumps end in landfill, and leave a large hole to fill
• The reach and flexibility of the excavator can prevent damage to plants and fixtures in the vicinity of the stump, by reaching over the obstruction or sensitive area.

Converting a Diamond Rocksaw to a Stump Grinder

Diamond rocksaws are well suited to conversion to stump grinding. The HS and HP models, which have very high speed (rpm) are the best options.

Specifications

If the rocksaw is only to be used for stump grinding and wood cutting, it is recommended that the reversible blade spin option be removed. This both reduces the price of the unit, and prevents the possibility of spinning the blade in the wrong direction.

Stump grinding requires a wider guard than the standard diamond rocksaw guards, to contain the chips of wood.
